Becoming a qualified electricity supplier/guarantee of capacity

By becoming a qualified supplier, you may bid in our calls for tender. We regularly need to purchase power or guaranteed capacity to offset distribution-network losses.

What is a qualified supplier?

A qualified supplier has been certified by Enedis to bid on its calls for tender.
These consultations are performed as Enedis has a legal obligation to purchase power to offset distribution-network losses and, in its capacity of mandatory stakeholder, cover the associated capacity guarantees. The power and capacity guarantee supplies may not be subdivided into a power of less than 1 MW or 10 capacity guarantees.

Would you like to apply?

To become an energy and/or guaranteed-capacity supplier, ask us for a qualification application file using the following email address:


To be accepted, the following must be enclosed with your application:

  • The signed letter of acceptance of the general terms and conditions of purchase.
  • The requested administrative, financial and tax documents (e.g., balance sheet, Balance Responsible Entity contract with RTE for energy qualification).


It will take about 2 months to process your application and, if necessary, configure your IT tools. Qualifications are reviewed annually.

To become a qualified power supplier, you must first be in possession of a prior authorisation from the government (Ministry for Ecology, Sustainable Development and Energy, Directorate-General for Energy and Climate).

The consultation and proposal approval

To purchase this power or these capacity guarantees, we frequently consult suppliers through open-market competitions.
These consultations are used for products that adhere to French wholesale market standards and for periods of up to 4 years.



  • For power: annual, quarterly and monthly baseload and peakload.
  • For capacity guarantee, the year of guarantee delivery.

We continually offset our distribution network losses based on medium- and short-term forecasts. To ensure that enough energy is available to offset these losses, we purchase electricity from both long-term and spot wholesale energy markets.

What is meant by energy “loss”?


There are 2 types of network electricity losses:

  • Technical losses due to the heating of conductors and transformers during electricity transmission.
  • Non-technical losses in which energy consumed cannot be billed to an end user. Reasons for these losses include: imprecise or incorrect readings, fraud and human error...


Losses represent nearly 6% of energy transmitted through the network, or about 20 TWh/year.

How is the energy report prepared and loss evaluation performed?


We perform an evaluation of energy losses using a network energy report. The report calculates the difference between our consumption load graphs and readings from all our customers. It takes into account energy waste (or loss) due to electrical phenomena in circuits and transformers.

Why do we cover for losses?


When the electricity market was opened up to competition, responsibility for offsetting losses was assigned to us.
We therefore purchase energy from qualified suppliers on long-term (4-year coverage) and spot wholesale electricity markets.

Further information

What do capacity guarantees correspond to for "losses"?


In application of Article L. 335-1 of the French Energy Code, each electricity supplier must contribute to electricity-supply security, as a function of the consumption characteristics of its clients, in terms of power and energy, for continental France.


Therefore, each electricity supplier must have load-curtailment capacity guarantees. These may be deployed to satisfy the offer and demand balance in France, in particular for periods of peak consumption.


To this end, the supplier must have a capacity guarantee for the energy deliveries it must make.
By applying the law (Article L. 335-5 of the French Energy Code), we wish to implement a transfer of obligation in relation to the capacity guarantees legally applicable to the supplier. We therefore cover the capacity guarantee for the energy supplied.
